Astronomy Edexcel GCSE (1AS0)

This subject is offered as a full GCSE option. It should be considered by those pupils who have a deep interest in the subject and want to add a fourth science to their (I)GCSE portfolio.

The course is structured in five lessons per fortnight and allocated two preps a week.

The examination consists of two papers each of 105 minutes; these papers count for 100% of the available marks. However, there is also a requirement to complete two observational projects. Observing can take place at any time over the course, including holidays, with clear weekday evenings in term time set aside for this and one observing session will count as a prep. If access to the Dome is not allowed, observations may be made by staff and accessed via live streaming.

The body of knowledge to be assimilated and the level of analysis that GCSE Astronomy questions demand, combined with the extensive subject specific terminology required, make this subject demanding. The subject is open to all interested pupils with the

motivation and potential to benefit from the course. Enthusiasm for Astronomy, and some skill in mathematics, are key to success in this GCSE.

The entire course is observationally based and observational experience is tested within the examination papers.

The course is broken down into two main topic areas:

• Naked-eye astronomy – examined in Paper 1 • Telescopic astronomy – examined in Paper 2

The following topics are studied:

Remove: Planet Earth. Celestial observation. Exploring the Moon. Exploring the solar system. Solar system observation. Early solar system models. Planetary motion and gravity. Solar astronomy. Time.

Hundred: The Earth-Moon-Sun system. Formation of planetary systems. Exploring starlight. Stellar evolution. Our place in the Galaxy. Cosmology.

Two pieces of observational work are undertaken over the two-year course. One of these must be unaided and the other aided, which will usually be completed at the College observatory. Projects may be selected from an extensive list provided by Edexcel.

Pupils are currently issued with the textbook GCSE Astronomy (9–1) – A Guide for Pupils and Teachers, by Nigel Marshall (5th Edition).

Astronomy Resources:

Edexcel maintains a dedicated website for the qualification:

http://qualifications.pearson.com/en/qualifications/edexcel-gcses/astronomy-2017.html

This contains an abundance of materials and resources, including copious worked examples and supportive handouts to address specific mathematics skills in many of the topics; copies of these are handed out in lessons. Astronomy Now magazine is available through the Memorial and Physics Libraries.

The course is taught using data from current research and the internet, especially using the free Planetarium software package, Stellarium. This is also available as an App.

For the practical work, pupils use a range of binoculars and telescopes at the College Observatory. The Observatory houses the largest telescope in Wiltshire, a 10-inch refractor (fully modernised, refurbished and also equipped for solar use), an 8-inch Newtonian reflector, two 4-inch reflectors and a 4-inch refractor. There are also multiple pairs of tripod-mounted 10×50 and 15×70 binoculars.

There is an expectation that GCSE Astronomers will attend the Observatory on dedicated clear nights if they are free to do so. Additional opportunities for observation may also be offered. Groups are encouraged to help record Meteor Shower data and may gather at the observatory for certain other ‘one-off’ events (e.g. Transits and Eclipses).
